The Late-Witness Contradiction
You act for the plaintiff in a Queensland Supreme Court personal injuries trial. Your client, Ms Tan, gave evidence that the defendant's truck ran a red light. During cross-examination, defence counsel produces a statement Ms Tan signed three days after the accident for her insurer, in which she wrote that she 'could not be sure' of the light colour. She denies writing it and says she signed without reading. Defence counsel seeks to tender the statement as proof of its contents. You object. The trial judge asks both counsel to address whether the statement can be used to impeach Ms Tan and, separately, whether it is admissible as evidence of the truth of its contents. The document is not under any statutory exception, and Ms Tan is available for further questioning. The judge wants submissions framed on both the credibility and hearsay axes before ruling.
1. Identify the evidentiary basis on which the prior statement may be used, and explain whether it can prove the truth of its contents.

The statement is a prior inconsistent statement. Under the common law and the Evidence Act 1977 (Qld), a witness may be cross-examined on a previous statement and, if the witness denies making it, the document may be put to the witness and proved. Its use is confined to testing credibility; it is not admissible as proof of the truth of its contents unless a hearsay exception applies. Because Ms Tan is in the witness box and denies the statement, counsel may prove the document to show the inconsistency, but the jury must be directed that the writing is not evidence of the facts stated. The tender as proof of contents would be impermissible hearsay. The trial judge should admit it only for the credibility purpose and give a clear limiting direction. The distinction matters because the defence wants to convert an impeachment tool into substantive evidence, which the hearsay rule forbids absent an exception.
2. Ms Tan says she signed without reading. How should the judge approach the weight and the fairness of admitting the document?

The judge retains a discretion to exclude or limit the use of the document where its probative value is outweighed by unfair prejudice or where its admission would be unfair to the witness. The witness's explanation that she signed without reading does not make the document inadmissible, but it bears on weight. The judge should consider whether Ms Tan had an opportunity to explain or contradict the statement, whether she was given notice of it, and whether the circumstances of signing (three days post-accident, insurer context) affect reliability. The judge may permit cross-examination on the document and a direction to the jury about the limited purpose and the witness's explanation. If the document was obtained in circumstances that would make its use unfair, the judge may exclude it under the general discretion. The ruling should be reasoned and should distinguish the credibility use from any substantive use, and should ensure the jury is not left with the impression that the statement is proof of the light colour.
